This invention relates to what may be termed a power unit adapted particularly for radio receiving sets, said unit consisting of a case equipped with a'storage batteryfor supplying current to the tubes when the set isin use and a charger for charging the case and without liability of heat transference betweenthe compartments containing respectively the battery and charger, and

without liability of'acid being carried over 7 in a finely divided state {from the'battery compartment to the charger compartment.

The invention may jbe herebriefly sum marized as consisting in novel *deta ls of construction and combinations and arrangemerits of parts which will be described in the specification. and set forth in the ap pended claims. In the accompanying sheets of drawings in which I have illustrated an embodiment which operates with high efiiciency Fig. 1 3o and'Fig. 2 are two side views with parts in section, the cover being shown by'dotted lines in Fig. 1; Fig. 3 is a top plan View with the cover removed; Fig. 4fisa side view looking toward the opposite "side to that shown inFig. 1; Fig. 5 is a bottom View of thecase, and "Fig'gfiis a top plan view of the cover.

- Referring now'to the drawingsythe unit,

includes a case 10 which: is preferably '16 formed of sheet'metal in rectangular shape and is provided with a sheetmetalcover 11-.

The interior of the case'isi divided prefer} 1 ably by a vertical, double walled partition into a battery compartment 14; and a charger 4 compartment 15. c c I In thecompartment 14 is located a storage battery 16 which may have any number of cells, but in thisinstance it is provided with three cells. While the cells of the battery may have individual containers or cellsicanbe seen. battery when theset is not in use, this j provided} fl his charger? may be of any suitable construction, the details of are immajterialgto the present invention and the positiveand' negative terminals of the.

j'ar s; in this instance 1*employ. a single multi-compartment glass jar 16 and the, side of tlie-container'lO opposite the three, compartments is provided with elongated slots 17 throug which the acid level of'the f AdditiOnalIyIthe end wall is preferably provided with a slot 18 opposite one of the end cells and through this slot may be seen gravity indicators ,placedinthe end cell to" indicateg the specific gravity of the elect-roe lyte,thisf end cell being providedwith an extension 19., (see Fig; 3) to accommodate the indicators whichare preferably inthe form-0f balls' capable ofri'sing or sinking 6 2 injth e" electrolyte as the specific gravity is varied.- j 4. 1 In the compartment. 15a charger 20- is "which itgfmay' have any suitable rectifying device. Inoiie "ofPthe 1 end walls of the compartment 15 a switchpanel 21 is provided, (see Fig. 2);,( which panel is equipped. with suitable binding posts 22 and switches 23 by which the'battery may beiconnected to the receiving set .or" to the charger, theltwo sets of binding p'osts'and the three switches making it possible also to" disconnect the'batteryin compartmentflt from the charger "and to connectjithe.charger to an outside battery, such. asa "B battery, {Connection is made from; thecharging circuit to the charger by means'offacablefl (seeFi'g. I) whichextends up thrQri'ghthe-bottom of the charger compartment 15. V V

AtJthe upper end of the charger two. ter-' 25 are. provided; these being adapted .to be connected by means offthe switches 23 [either to the receiving set'orthrough'the charger-to the charging circuit these'terminals :being connected by conductors26 to battery. I It 'iwill beobserved that thedouble walled partition "18 projects up above they top of the container body (note particular1y""'Figs.; 1 ,-2 and 4:) and that :the con ducto rs 25-exte'nd through 'ope'ningsyin the V 193 partition a suitable distance down from the top thereof.

The two walls forming the partition 13 are spaced apart forming a flat, Vertically disposed air duct open both at the top and the bottom so that it is possible fora stream of air'to pass upwardly between the battery compartment and the charger compartment, in V thus minimizing the heat transference between the two compartments, the escape ofwarm air at the top being facilitated by a large number of ventilating openings 27 (Fig; 5) provided in the cover." 'Thebot:

tom walls of both compartmentsmayrbe provided with openings 28 (Fig. 6), so that there may be an upward circulation of air.

through the compartments,themselves as;

comprising two spaced Walls, and a cover having a bafile extending downwardly between and spaced from the walls of said partition.

In testimony whereof, I hereunto aflix my signature.

THEODORE; A. WILLARD.

well as between the walls formingthelpar- V tition 13.

Additionally, the cover is preferably pro vided with a bafile 29, which, when the cover is in place, extends down for a; short distance between. and beneath the upper edges of the walls forming the partition- 13, thus minimizing the likelihood' of acid in spray form being carried overiromthebattery compartment to the charger com partment. p

By the above arrangementthe parts c011;- stituting the unit are, compactly arranged, it beingpossible by reason of thecentral air duct to have the battery and charger close together without liability of the charger e heating the battery, and by the overlapping arrangement of the bafiieQ andthetop edges of the double walled partition thev charger is not likely to be injnred by acid even though the two compartments are'not wholly a separated. e i

Whilev I have shown the. preferred ,em-

bodiment of the invention, I do not, desire tobe limited to the precisev detailsshown, but aim in my claims to coveralli modifica tions which do not involve a. departure from the spirit and scope of my invention, Having thus described my invention, I claim:

1. A container having twdco'mpartments v with a double walled,iverticalfpartition sep; arating the compartments, said double Walled partition formingalvertical air duct open at the top and extending through the bottom of the container.

2. A container comprising a-ca'sehaving between the two walls of the partition and i is spaced from eachiof them.

3; A container having a; vertical, partition forming two compartments, said, partition
